Objective To investigate the reasons for missed diagnoses of children's chest complex fractures in chest radiographs and to discuss the value of multi-slice spiral CT (MSCT) reconstruction in the diagnosis of children's chest complex fractures. Methods 123 children underwent chest digital radiography(DR) and MSCT scans after traumas were collected in our hospital between January 2012 and August 2015. This population consisted of 81 male and 42 female patients, with a mean age of 4.3 years(range from 9 months to 15 years). All participants underwent chest MSCT scans in 1-3 days after completing chest DR, and then we used 3D reconstruction to process the data and compared the results with those processed by DR. Results By chest DR tests we identified 39 cases (61 places) out of 123 participants with 24 simple fractures, 15 complex fractures. And 48 chest fractures were suspected. We also identified 36 cases had chest complications without fracture. By MSCT scans 76 cases (142 places) were identified, among which 42 were simple and 34 were complex. Compared with chest DR, MSCT scans can identified 18 more places of simple fractures and 63 more places of complex fractures. It was statistically significant higher detection rate of MSCT scan than DR. Conclusion Chest MSCT scan combined 3D reconstruction technology can increase the detection rate of chest complex fracture. Compared with DR, it provides more detailed and visualized information, including fracture position, type, severity and adjacent structure damage. It has important guiding value on the selection of therapy and prognosis evaluation.

Objective To survey on the recognition and diagnosis capability of frontline healthcare workers in boy's genital malformation in Shufu, Xinjiang. Thereby to provide data support for the healthcare workers training there. Methods We designed a questionnaire and carried out a survey in Shufu people's hospital, township clinics and village doctors. Based on SPSS 13.0 data analysis, we made comparison on recognition difference between the Han and Uygur healthcare workers. Results 400 questionnaires were handed out, among them 365 were valid which accounted for 91.25%. The survey showed that there were 54.79% survey participators whose recognition correct rate was over 50% in Shufu, Xinjiang (21.92% for man, 32.87% for woman), 50% Han healthcare workers whose recognition correct rate was over 50% and that of 57.4% in Uygur peers.There was no significant difference in statistics(P<0.05). It accounted for 38.36% that participating in training as the access to relevant knowledge of genital malformation,but 61.64% was not. In clinical practice, 86.3% of survey participators screen the possibility of newborn genital malformation. And 27.39% of screened newborn have genital malformation. Conclusion The frontline healthcare workers in Shufu, Xinjiang at large are short of diagnosis knowledge on boy's genital malformation, as a result that they are difficult to recognize and give proper treatment on such cases in practice. The status thereby shows that it is critical to improve the diagnosis and treatment capability of frontline healthcare workers in boy's genital malformation in Xinjiang ethnic group area.
